CATIA Interface, Shortcuts, and File Format Guide

CATIA · Shortcuts & UI

Overview

This page is a fundamentals primer for both newcomers and seasoned CATIA practitioners. It consolidates the product lineage (V4 through 3DEXPERIENCE), the on-screen anatomy (Workbench, Compass), keyboard and mouse handling, and file-format selection criteria in one place.

The goal is to lock down the interaction rules here first before they recur across the later pages (Part Design, Assembly, GSD, and so on).

1. CATIA Product Lineage at a Glance

CATIA (Computer Aided Three-Dimensional Interactive Application) originated in 1977 at Dassault Aviation in France as an in-house tool for designing the Mirage fighter. After Dassault Systèmes was spun off in 1981 and struck a distribution partnership with IBM, CATIA grew into a commercial CAD/PLM platform.

Today it is used broadly across automotive BIW and powertrain, aerospace structures and electrical, shipbuilding, heavy industry, and plant.

Generation	Era	Characteristics	Current Status
V4	1993 – early 2000s	UNIX only	Legacy (lingers in some aerospace programs)
V5	1999 – present	Rewritten for Windows NT onward, file-based	Industry mainstream
V6	2008 – 2014	ENOVIA DB-centric	Absorbed into 3DEXPERIENCE
3DEXPERIENCE	2014 – present	Cloud / on-premise PLM platform	Default for new customers

Tip When people in the field say "we use V6," they almost always mean early 3DEXPERIENCE. Since 2020, virtually every new customer has started directly on the 3DEXPERIENCE lineup.

Note .CATPart files can be imported or converted into 3DEXPERIENCE, but Knowledgeware rules and complex parameters are not fully preserved. For migration projects, always run a sample-part pilot up front.

2. V5 vs. V6 vs. 3DEXPERIENCE

Axis	V5	V6	3DEXPERIENCE
Data storage	Files (.CATPart / .CATProduct)	ENOVIA DB	3DXML + Platform DB
Initial screen	Classic Workbench	V5-like + ENOVIA	Compass-based App structure
Collaboration	File sharing	Built-in PDM	Real-time cloud collaboration
Licensing	Perpetual / partner	Perpetual	Role-based subscription
Installation	Local PC	Local + ENOVIA server	Cloud or on-premise
Release cycle	R21 – R32	Discontinued	Quarterly (R2020x – R2025x …)

Instead of "workbenches," 3DEXPERIENCE uses a Role → App hierarchy. Users first pick their Role (job function), then launch individual Apps from within it.

3. V5 Workbench Map

V5 opens a Workbench per functional group. The menu path is Start → Category → Workbench.

Knowledgeware: Knowledge Advisor / Expert, PEO, BKT
Ergonomics: Human Builder / Activity / Posture Analysis

4. The Role Concept in 3DEXPERIENCE

In 3DEXPERIENCE you search for and launch apps from the Compass (circular icon on the left edge). Representative Roles include:

Mechanical & Shape Designer (MDG) — counterpart to V5 Part / Assembly
3D Part Design Engineer (PDE) — extended Part Design
Generative Shape Designer (IGD / GSE) — counterpart to V5 GSD
Function-Driven Generative Designer (FGD) — topology optimization
Class A Designer (AS1 / AS2) — ICEM family
Drafter (DRA) — Drafting
xDesign / xShape / xGenerative Design — lightweight browser-based designers

→ See also: /cad-tips/catia/part-design.md for part modeling details, and /cad-tips/catia/assembly-dmu.md for assembly and DMU.

5. Essential Keyboard Shortcuts

Below are V5 default shortcuts pared down to the ones you actually use daily in practice.

Key	Function
`Esc`	Cancel command / close dialog
`F1`	Help
`F3`	Toggle Specification Tree
`Shift+F1`	What's This?
`Shift+F2`	Tree Overview window
`Shift+F3`	Switch Tree to active object
`Ctrl+Z / Y`	Undo / Redo
`Ctrl+C / V / X`	Copy / Paste / Cut
`Ctrl+F`	Search
`Ctrl+N / O / S / P`	New / Open / Save / Print
`Ctrl+U`	Manual Update
`Ctrl+E`	Edit / Modify dialog
`Alt+F4`	Close window
`Alt+F8`	Macro window
`Alt+Enter`	Properties
`← → ↑ ↓`	Pan view
`Shift+Arrow`	Rotate about X / Y axis
`Ctrl+Shift+Arrow`	Rotate about Z axis
`Ctrl+Page Up/Down`	Zoom In / Out
`Home / End / PgUp / PgDn`	Tree navigation

6. Custom Shortcuts You Should Set Up Yourself

Menu path: Tools → Customize → Commands → Accelerator. The combinations below are the ones that move the productivity needle the most in real work.

H — toggle Hide / Show
Shift+Space — Swap Visible Space (visible space ↔ hidden space)
I — Isolate (selected items only)
F — Fit All In
N — Normal View
U — Manual Update
M — Measure Between
R — Reframe On

Tip At Korean manufacturers it is a common practice to bundle the Ctrl+Shift+ family into a company-wide custom-shortcut convention and roll it out across the organization. It is a reliable way to shorten onboarding time for new hires.

7. Three-Button Mouse Operation

A laptop trackpad is effectively unworkable for real tasks. A wired three-button mouse is the baseline kit.

Action	Result
Left-click	Select
Ctrl + left-click	Multi-select
Middle-button + drag	Pan
Middle-button + right-click toggle	Zoom (drag up/down)
Middle-button + left/right simultaneously	Rotate
Scroll wheel	Zoom In / Out
Middle-button double-click (any point)	Set that point as the rotation center
Right-click	Context menu
Double-click a tree item	Edit / Define
Double-click a Sketch	Enter Sketcher

Key tip: At the start of a session, double-click the middle button on a chosen point to pin the rotation center. In large assemblies, failing to pin a rotation center frequently flings the view off-screen.

8. 3Dconnexion SpaceMouse

In my experience more than half of working CATIA users pair a SpacePilot or SpaceMouse Pro / Enterprise with a regular mouse.

The left hand handles six-DOF view manipulation while the right drives selection, which measurably reduces fatigue and cycle time.

Learning period: one to two weeks
Reported productivity gain afterward: 20 – 40%
Configuration path: Tools → Options → General → 3Dx Devices for sensitivity and axis inversion

Because these are officially supported Dassault Systèmes devices, driver compatibility is effectively a non-issue.

9. Compass (Upper-Right Gizmo) Handling

The Compass is a three-axis gizmo that handles everything from view alignment to moving parts — all in one widget.

Click the X / Y / Z label — align that axis to point out of the screen (e.g., normal view to the XY plane)
Drag an arc — rotate about that axis
Drag an axis — translate along that axis
Drag the red square and snap to an object — freely translate / rotate the part or product
Right-click — Edit Position, Lock Current Orientation, etc.

Key tip: When you need to rough-position a part in an assembly before applying Constraints, drop the red square of the Compass onto the part and drag. You can align freely without any constraints, which is indispensable for preliminary placement.

Note A part moved with the Compass only moves relative to the current Product coordinate system. To move it relative to the parent assembly coordinates, activate the top-level Product first.

10. File Format Selection Criteria

10.1 V5 Native Formats

.CATPart — single part (Solid / Surface / Wireframe Body + Parameters + Relations)
.CATProduct — assembly (holds reference links only, no geometry)
.CATDrawing — 2D drawing (linked back to 3D references)
.CATAnalysis — GSA analysis
.CATProcess — NC manufacturing
.CATScript / .catvbs — macros
.catalog — catalog (standard parts)
.CATMaterial — material library
.CATDrwStandard — drawing standard

10.2 Neutral Format Comparison

STEP (AP203 / AP214 / AP242) — industry standard. AP242 carries PMI as well.
IGES — legacy, surface-only. Quality issues are frequent.
STL / 3MF — 3D printing.
JT — Siemens lightweight format, common in airline data exchange.
CGR — CATIA-proprietary tessellation. The internal representation for Visualization Mode.
3DXML — Dassault's web-review format.
Parasolid (x_t) — for exchange with Siemens NX.

Tip For automotive OEM–supplier exchanges, STEP AP242 combined with JT is effectively the current standard. In large aerospace programs, CATIA V5 native or JT still dominate.

Note Compatibility across CATIA releases is forward-only. You can open an R21 file in R29, but you cannot open an R29 file in R21. There is no official downgrade path, so your team must standardize on a single CATIA version.

Field Checklist

Evaluate introducing 3Dconnexion SpaceMouse
Register a company-wide custom shortcut set (H, I, F, N, U, M, R, Shift+Space)
Build the habit of pinning the rotation center with a middle-button double-click
Rough-align with the Compass before applying Constraints
Fix the default external exchange format to STEP AP242
Set up a parallel JT export flow (for automotive collaboration)
Standardize the CATIA release across the company (knowing downgrades are impossible)
For 3DEXPERIENCE migrations, pre-validate conversions with a sample pilot
